BACKGROUND
The dental practitioner's most important tool is light to see the teeth he is working on. This light is most often provided by a large dental lamp that is suspended in front of the patient's mouth and at the same time, behind the dental practitioner. This common method of mouth illumination has several limitations. The dental practitioner must frequently adjust the lamp position in order to illuminate portions of the patient's mouth. The dental practitioner's head is often blocking the light because the lamp is behind the dental practitioner. Often the dental practitioner's hands and tools block the path of light. An alternative has been to put a light on the end of the dentist's drill handpiece to illuminate the operation field. However, this only works when the drill is in use and is not good for just an examination of the mouth and it only concentrates exactly where it is pointed. For exams the practitioner is subjected to only using a pen light or similar type device in addition to the overhead lamp.
This present invention solves both of these problems by placing the light source inside the patient's mouth. A light source composed of an array of light emitting diodes (LEDs) or some other light source secured inside the patients mouth provides abundant light where it is required. The dental practitioner can now move his head to better see his work and move his hands without blocking the light.
SUMMARY
This invention gives the dental practitioner abundant light at the area of the mouth where he needs it. An array of low voltage cool operating LEDs is placed at a convenient location in the patient's mouth or on top of a few teeth on the side of the mouth opposite from where the dental practitioner is working. The array of LEDs may be secured on top of these teeth by a clamp or by some other means. Power for the array of LEDs is provided by an internal battery or by a small power pack that may rest in the patient's lap.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
One embodiment of the Inside Mouth Dental Light is illustrated in FIG. 1 where an open patient's mouth 10 is seen to be illuminated by this unique invention. The complete attached light assembly 12 is secured to a few teeth on the right side of the mouth. Light beams 14 are illuminating both the left side of the mouth where the dental practitioner is working and the right cheek. When the dental practitioner is finished his work on the left side he will move the attached light source assembly 12 to the left side where the LEDs 18 will now illuminate the right side of the patient's mouth and the left cheek. In both locations of the attached light assembly 12 the thin wire 15 that supplies power to the light assembly is emerging from the end of the assembly that is facing the dental practitioner.
FIG. 2 shows another embodiment of the Inside Mouth Dental Light where the dental practitioner has more freedom to use the free light assembly 11 at any location with the mouth 10. The LEDs 18 are located at many and various places on the free light assembly and the beams of light 14 are able to illuminate hard to reach mouth 10 locations. The free light assembly 11 may contain only one light source as more advanced light sources become available that are appropriate for dental use.
FIG. 3 shows one embodiment of the complete invention where light assembly 12 is attached to the power pack 28 by means of wire 15. Switch 26 provides a way for the user to turn on the light or to turn it off.
FIG. 4 illustrates a more detailed view of one embodiment of the Inside Mouth Dental Light. A light source enclosure 16 supports the array of LEDs 18. There are other types of light source than can be used here as well as the LED. The filament incandescent bulb is just one example. The LEDs 18 protrude from light source enclosure 16 and supply light in several directions so the dental practitioner can use the light array on either side of the patient's mouth. The light source enclosure 16 is secured to a few teeth or to a gum when there are no teeth by a securing clamp 20. A temporary type of glue or suction method might also be used to secure the light source enclosure.
FIG. 5 shows the Inside Mouth Dental Light with a single light source 17
FIG. 6 shows one embodiment of the complete invention where the power source is inside the light assembly 12. The light source enclosure 16 supports the LEDs 18, a battery compartment 32, and a push button switch 34 that the dental practitioner would use to turn on and off the light source.
FIG. 7 provides an electrical schematic for only one of many ways that this Inside Mouth Dental Light can operate using an external power pack. In one embodiment the LEDs 18 along with their current controlling resistors 22 are secured inside the aforementioned light assembly 12. Each LED 18 in the array of LEDs is in series with a resistor 22 that controls the current to the individual LED 18. Battery cells 24 along with switch 26 located inside the power pack 28 provide electrical current through wire 15 for the LEDs 18.
FIG. 8 provides an electrical schematic for only one of many ways that this Inside Mouth Dental Light can operate using an internal power pack. In one embodiment the LEDs 18 along with their current controlling resistors 22, battery cells 24, and push button switch 34 are secured inside the aforementioned light source enclosure 16. Each LED 18 in the array of LEDs is in series with a resistor 22 that controls the current to the individual LED 18.
Although the description above contains many specificities, these should not be construed as limiting the scope of the invention but as merely providing illustrations of some of the presently preferred embodiments of this invention.
Operation
The dental practitioner may use the Inside Mouth Dental Light in place of the more conventional dental lamp or as a supplement to that lamp. As he prepares the patient's mouth for examination or dental work on the left side of the patient's mouth the dental practitioner will place the new light source assembly on the teeth in the patient's right side.
For the embodiment with an external power pack, he will place the power pack on the patient's lap or clip it to a convenient place on the patient's clothes. He will turn on the power pack switch and work on the left side of the patient's mouth. When he is completed with the left side he will reverse the process on the right side with great ease.
In another embodiment of The Inside Mouth Dental Light where there is no clamping device, this light source may be place at any location inside the patient's mouth.
